set position allocator

[Seasong]

Hey guys, when I compile my c file it says
no matching function for call to
‘ns3::MobilityHelper::SetPositionAllocator(const char [35], const char
[9], ns3::Vector3D)’

Below is my script for this part:

MobilityHelper mobility;

mobility.SetPositionAllocator ("ns3::ConstantPositionMobilityModel",
"Position", Vector3D (-5.5,3.0,0.0));

Where am I wrong?

I can be wrong but I think this function only accepts std::string. Try to pass std::string instead of char array.

HI,

I usually follow this:

Ptr<ListPositionAllocator> positionAllocS = CreateObject<ListPositionAllocator> ();

positionAllocS->Add(Vector(-10.0, -10.0, 0.0));// node

MobilityHelper mobilityS;

mobilityS.SetPositionAllocator(positionAllocS);

mobilityS.SetMobilityModel("ns3::ConstantPositionMobilityModel"); //whatever it is

mobilityS.Install(node);

just for future references....

mobility.SetMobilityModel ("ns3::ConstantPositionMobilityModel",
"Position", VectorValue (Vector (-1.0, -1.0, 0.0)));

works

Dear Luca,

If I want to fix the position of one node, the rest is randomly distributed. How can acheive this? if I use mobility.SetMobilityModel ("ns3::ConstantPositionMobilityModel",
"Position", VectorValue (Vector (0.0, 0.0, 0.0))); and install mobility into nodes, it will be installed into all node, right?

Thank you in advance.

Best Regards,

ZM

I'm confident that Luca will reply to this post. It's "just" 2 years and 3 months old.

As a consequence, I'll not reply. I'll wait patiently for Luca's reply. He will for sure. 100% !

For viewers from the future like myself: this doesn't seem to be the case anymore.  You get the error msg="Attribute name=Position tid=ns3::MobilityModel: initial value cannot be set using attributes", file=../src/core/model/object-base.cc, line=112

8 years later this works- ns3.30.1.  Thank you!
